Detailed Description

ApplyJES applies JES corrections to a list of jets (overwrite JES corrections). The output list of jets is stored in a separate branch. The implementation mimics the one into d0correct.

Required parameters:

• .From: Name of the branch the jets are selected from

Optional parameters:

• .Tree: OutputTreeName[default: name()]
• .To: Name of the branch the jets are written to (default: .From branch name)
• .muonBranch: Name of the muon branch used to match muon with jets (if this branch is not set, will use the same list of good muons as in d0correct as default)
• .JetEnergyScale_datatype: type of JES to be applied: data or MC (default: determined automatically)
• .JetEnergyScale_jetalgo: type of jet algorithm used as input (1=JCCA, 2=JCCB)
• .doJESMU: decide if you want to compute the JES for muon in jets
• .MuoTagdR: maximum dR between muon and jet to determine if a muon is matched to a jet
• .MuoTagPtrel: maximum projection of the muon pt on the jet pt axis to determine if a muon is matched to a jet
• .AddDataErrorsToMC: add statistical and systematics data errors to the MC errors (default: false) using formula
  err_syst_kJES_mc = kJES_mc * sqrt( (err_stat_kJES_data/kJES_data)**2 + (err_syst_kJES_data/kJES_data)**2 + (err_syst_kJES_mc/kJES_mc)**2 )
  Total error shoudl be calculated as
  err_tot_kJES_mc = sqrt(err_stat_kJES_mc**2 + err_stat_kJES_mc**2)

• .Debug: debug print out
• .p1803CAFPatch: apply patch to the fake jet pt Present in the p18.03 CAF. Will not affect correct pt [default: true]
